"With the Star Walk app, if you hold your iPod up towards the sky, you can see all the stars and constellations. It even tells you the names of all the planets. Then, if you point it towards the ground, it shows you what all the stars are in the other hemisphere. It’s brilliant, and if you’re ever somewhere with a clear sky and no light pollution, it’s a revelation. It’s beautifully designed and makes clever use of the available technology. I’m fascinated by astronomy, but even if you’re not, give this a go."
